Differential solute clearances were used to characterize glomerular function in 12 nondiabetic subjects with severe obesity (body mass index >38). Nine healthy subjects served as the control group. In the obese group, glomerular filtration rate (GFR) and renal plasma flow (RPF) exceeded the control value by 51 and 31%, respectively. Consequently, filtration fraction increased. The augmented RPF...
This study examined the role of tissue kallikrein and kinins in renal vasodilation produced by infusion of amino acids (AA). In rats fed a 9% protein diet for 2 wk, intravenous infusion of a 10% AA solution over 60-90 min reduced total renal vascular resistance and increased glomerular filtration rate (GFR) by 25-40% and renal plasma flow (RPF) by 23-30% from baseline. This was associated with ...
BACKGROUND/AIMS Retroperitoneal fibrosis (RPF) is a chronic inflammatory disorder causing obstructive nephropathy and renal failure. We reviewed our management of this condition. METHOD All patients with RPF treated at a single center over a 15-year period were identified. A full review of notes and computer records was undertaken. RESULTS Data was available on 27 patients, 3 of which were ...
Determination of renal plasma flow (RPF) by para-aminohippurate (PAH) clearance leads to gross underestimation of this respective parameter due to impaired renal extraction of PAH after renal ischemia and reperfusion injury. However, no mechanistic explanation for this phenomenon is available. Based on our own previous studies we hypothesized that this may be due to impairment of expression of ...
OBJECTIVE To evaluate the therapeutic effect of tamoxifen monotherapy in patients with retroperitoneal fibrosis (RPF). PATIENTS AND METHODS From 2007 on, 31 patients with idiopathic RPF were treated with tamoxifen monotherapy. Follow-up investigations included magnetic resonance imaging, laboratory measurements, registration of side effects and changes or removal of ureteral stents. Data were...
Infusion of indomethacin into anesthetized, salt-depleted dogs cuased an increase in mean arterial blood pressure (MABP), and decreases in heart rate (HR), urine flow rate (V), renal plasma flow (RPF), and renin secretion rate. MABP was 112.1 +/-5.4 mm Hg during control periods and was 147.7 +/- 5.6 mm Hg (P less than 0.005) 80 minutes after the infusion of indomethacin. V was 0.38 +/- 0.06 ml/...
In previous studies we have shown stimulation of renal acid excretion in the proximal tubules of rats with diabetes of short duration, with no important alterations in glomerular hemodynamics; on the other hand, in thyroparathyroidectomized rats (TPTX model), a significant decrease in renal acid excretion, glomerular filtration rate (GFR) and renal plasma flow (RPF) was detected. Since importan...
GFR and renal plasma flow (RPF) decrease in preeclampsia, a serious hypertensive complication of pregnancy. Serial data derived in late pregnancy (LP) and >5 mo postpartum (PP) in 13 healthy controls and 10 preeclamptic women (13 and 5, respectively) returning PP for theoretical analysis of neutral dextran sieving curves (theta(D)), are presented and are used to calculate the key determinants o...
The rpf genes and colS XOO1207/colR XOO1208 were known to require for virulence of Xanthomonas oryzae pv. oryzae (Xoo). In Xoo KACC10331 genome, two more colS/colR genes, colS XOO3534 (raxH)/colR XOO3535 (raxR) and colS XOO3762/colR XOO3763 were annotated. The colS XOO3534/colR XOO3535 were known to control AvrXa21 activity and functions of colS XOO3762/colR XOO3763 were unknown in Xoo. To char...
Glomerular filtration rate (GFR) and renal plasma flow (RPF) were measured by constant inulin and PAH infusion during euglycemia and intravenous dextrose-induced moderate hyperglycemia in seven insulin-dependent diabetics with persistently elevated GFR, seven diabetics with normal GFR, and in six normal control subjects. In euglycemia, RPF was higher and calculated renal vascular resistance (RV...
